3) Select preliminary outdoor units
Ô
Before selecting outdoor units, decide the permissible combination rates for indoor and outdoor unit.
➊
Determining permissible combination rates for indoor and outdoor units: Below 110%
❷
Calculate the sum of total capacity of the selected indoor units: 52.9kW (Refer to the table below)
52.9kW = [3.6kW + 7.1kW + 5.6kW + 7.1kW + 11.2kW + 7.1kW + 11.2kW]

Therefore, as 52.9kW/1.1 should meet outdoor unit capacity and less ( 52.9 kW/1.1
≤
outdoor unit capacity), cooling
capacity of outdoor unit should be larger than 48.1kW.
Hence, select the outdoor unit RVXVHT180GE(refer to the table below).
